Morphology

instillation = instill (semi-transparent) = in + still + ation

The word 'instillation' is derived from 'instill' with the suffix '-ation', indicating the act of instilling. However, the specific medical context may not be immediately apparent to all learners.

Etymology

Instillation comes from Latin parts in- 'into' and stilla 'drop'. It paints a simple image of putting liquid 'into' a body one small drop at a time, which is why it means the act of giving medicine drop by drop.
